* function profiling rewritten - more detailed info, supports global profiling (Vern Paxson, Corelight)
Hashes for Zeek script types are now done globally rather than
per-function-body, which can save considerable time due to the complexity
of some commonly used types (such as connection records).
Hashing has been expanded to provide more robust distinctness
(lack of collisions in practice) and determinism (consistently computing
the same hash across compilations).
